Donald Trump held his first post-Iowa campaign event in Milford, where he was joined by former Massachusetts Sen. Scott Brown.

Brown endorsed Trump during a press conference and a rally Tuesday night.

"The one person who has the independence and can be the change agent and can get Washington working again. It was very clear to me that was Donald Trump,” said Brown.

They held a joint press conference together, but almost all of the questions were about Iowa.

"Everybody wanted his endorsement and I'm very honored that he's giving it to me,” said Trump.

A lot of the national media tried to provoke Trump into being more expressive about what happened, but Trump did his best to just kind of brush off the loss.

From what he told the crowd, it was clear that the way this is being portrayed is getting under his skin.

"I think that we did very well. I did not expect to do so well. I guess what did happen is one poll came out that said I'm four or five points ahead and that maybe built up a false expectation for some people,” said Trump.

While he kept his cool with the media, Trump let a little New York slip into his vocabulary in his stump speech, swearing twice -- once talking about Russia.

"Let them use some of their weapons that cost billions and billions of dollars, let them beat the [expletive] out of ISIS."

“You watch, the Democrats, they've already said they're going to sue him. He gets the nomination they're going to sue his [expletive] off,” said Trump.

But the crowd ate up their unconventional candidate sounding nothing like a typical politician.

Supporters said they’re not worried at all about what happened in Iowa.

"I wouldn't say he didn't win. As a first time in the whole politics business, especially going for the highest office, I think second place is pretty good in Iowa,” said Eric Roberts, of Leominster, Massachusetts.
